英文摘要：

In order to achieve comprehensive performance testing for the water lubricated stern tube bearing and its transmission system, a test bench for this purpose has been developed. The test scheme is introduced. And the major structure of the test bench is designed and its dynamics is analyzed. The result indicates that the structure wouldn＇t resonate. The test bench can simulate the complex working conditions of water lubricated stern tube bearing and its transmission system. And the working speed, torque, temperature and friction characteristics of water lubricated stern tube bearings ; orbit of shaft center, noise ; pressure distribution, dynamic stiffness coefficient and damping coefficient of water film, and other parameters can also be tested online. It provides experimental conditions for the critical scien- tific problems such as establishing the systematic experiment and evaluation system of water lubricated stern tube bearing, studying on water lubricated friction pairs＇ load bearing, failure mechanism, evolution rule, tribological property, dynamic behavior and so on.
